The cyber attack was in response to the downing of an unmanned US surveillance drone last Thursday. It was carried out on the same day President Trump decided against bombing three sites in Iran at...
The news: The attack on Iran was conducted by US Cyber Command, targeting computer systems used to control rocket and missile launches, according to the Washington Post. There were no deaths and it was deemed “very” effective, officials told the Wall Street Journal. US officials declined to comment on the attack. Vice President Mike Pence told CBS: “We never comment on covert operations” in an interview yesterday.
Long time coming: The attack had been in the works for weeks, if not months, but it’s likely that escalating tensions in the region accelerated its launch. President Trump said Iran will face "major" new sanctions today.
Blurring boundaries: There is much we still don’t know about the attack: how it was carried out, exactly what the target was, how it worked technically, and so on. However, it’s a clear example of the way the lines between physical and digital warfare are blurring. Last month Israel launched a missile attack on Hamas operatives it said were engaged in cyber warfare, for example.

America is limiting big Chinese computing firms’ access to US tech for the super-powerful machines....
The news: According to the Wall Street Journal, the US Department of Commerce has imposed new restrictions on tech exports that will prevent five big Chinese makers of supercomputers from using US components. The restrictions will impact sales to the firms by US chipmakers such as Intel, AMD, and Nvidia.
The targets: The companies affected include Sugon of Beijing and three of its affiliates, as well as the Wuxi Jiangnan Institute of Computing Technology. The Commerce Department says Sugon has acknowledged that the Chinese military is among its customers. Wuxi Jiangnan is owned by the Chinese People’s Liberation Army.
Why hit supercomputers? Because the gargantuan machines aren’t just used for things like climate modeling and materials research. They also help develop nuclear weapons and other military gear, and they are increasingly powering leading-edge AI research, too.
Exascale rivalry: America still boasts the most powerful supercomputer in the world, called Summit, but both it and China are racing to develop the first "exascale" machine that will be five times faster. Every person on Earth would have to do a calculation every second of every day for just over four years to do what an exascale computer will do in the blink of an eye. The US’s move to restrict hardware exports could give it an edge in this contest, but it’s also likely to accelerate China’s efforts to develop homegrown chip suppliers.
